WebbTaking this requirement in our mind, in this paper we provide a general theoretical analysis of various M-ary PSK ( M = 32.64,128,256 & 512 ) modulation schemes using MATLAB Simulink model taking BER as measure of performance when the system is subjected to multipath Rayleigh fading channel. WebbThe example model simulates QPSK transmission over a multipath Rayleigh fading channel and a multipath Rician fading channel. Both the channel blocks are configured …
WebbRayleigh Fading is a commonly used term in simulation of Digital Communication Systems but it tends to differ in meaning in different contexts. The term Rayleigh Fading as used above means a single tap channel that varies from one symbol to the next. It has an amplitude which is Rayleigh distributed and a phase which is Uniformly distributed.
